摘　　要：为了解发酵床养猪的疫病风险,采用细菌常规分离鉴定、小白鼠攻毒、寄生虫虫卵检测方法,分别对5个养猪发酵床垫料和养猪场常规圈舍粪污内的致病菌和寄生虫虫卵进行了检测。结果显示：在发酵床垫料内分离到25种（亚种、类）致病菌,而常规饲养圈舍粪污内分离到8种（亚种、类）致病菌;发酵床垫料和常规饲养圈舍粪污内的同种致病菌的致病比较,发酵床内致病菌的致病性高于常规饲养圈舍粪污内致病菌的致病性。3个发酵床养猪时间延长1年后,发酵床垫料中的致病菌增加了4~9种（亚种、类）,其中1个发酵床的病原菌种类是1年前的3.25倍;5个养猪场的8个发酵床垫料中,有5个发酵床垫料内寄生虫虫卵呈阳性,即阳性率为62.5%,寄生虫种类为蛔虫和毛首线虫,其中,蛔虫虫卵有4个发酵床垫料呈阳性（阳性率50.0%）,毛首线虫虫卵有4个发酵床垫料呈阳性（阳性率50.0%）,对患寄生虫病最严重的1头猪进行解剖,其大肠黏膜上布满了毛首线虫。结果表明,发酵床养猪疫病风险高,不符合健康养殖范畴。For understanding of the risks of epidemic diseases caused by fermentation beds, the pathogenic bacteria and parasite eggs from the fermentation mattress materials and wastewater samples in the breeding houses of 5 pig farms were examined using conventional bacterial culture, parasite egg count and mouse inoculation. As a results, 25 species of pathogenic bacteria were detected from fermentation mattress materials and 8 species of pathogenic bacteria from breeding pig houses. There was higher intensity of pathogenic bacteria in the fermentation mattress materials than wastewater samples. Additionally, there were 4~9 more bacterium species found in the first year than the second year on 3 pig farms. The parasite eggs from the 5 fermentation beds were positive, including Ascaris suum and Trichocephalus suis. The results indicated there were high risks of epidemic diseases caused by fermentation beds.
